SIP Calculator Inflation Adjusted
Your SIP Calculator Inflation Adjusted separates what your corpus is worth on paper from what it can actually buy — enter your monthly investment, expected annual return, annual inflation rate, and investment period to see both your nominal maturity value and the real value after inflation, plus the inflation impact and real rate of return. The year-wise table traces the divergence between nominal and real systematic investment plan values at every annual checkpoint, so you know how much purchasing power your final corpus actually represents.

What is the SIP Calculator Inflation Adjusted?
The SIP calculator inflation adjusted adds a fourth dimension to standard systematic investment plan projections: purchasing power. A standard SIP calculator shows you the nominal maturity value — the face-value rupee amount your corpus will be worth at the end of your investment period. The inflation-adjusted SIP returns calculator goes further, showing you the real value — what that corpus is worth in today's rupees after the cumulative effect of inflation has been stripped out. If your SIP generates ₹50 lakh in 20 years but India's inflation averages 6% over that period, that ₹50 lakh will buy what roughly ₹15.6 lakh buys today — the inflation SIP calculator shows you that gap explicitly.
The real SIP returns calculator also shows the real rate of return — the return on your systematic investment plan after subtracting inflation, calculated using the Fisher equation: (1 + nominal return) / (1 + inflation rate) − 1. This single number tells you how much your wealth is genuinely growing in real terms, beyond just keeping pace with rising prices.

How Inflation Erodes Your SIP Returns
Inflation does not reduce your account balance — it reduces what that balance can buy. The inflation impact output shows the difference between your nominal corpus and its real purchasing power equivalent. At 6% annual inflation — roughly India's long-term average — prices double every 12 years. So a 20-year SIP target needs to be set much higher than the goal amount in today's rupees:
| Goal (today's value) | Required corpus in 10 years (6% inflation) | Required corpus in 20 years (6% inflation) |
|---|---|---|
| ₹25 lakh | ₹44.8 lakh | ₹80.2 lakh |
| ₹50 lakh | ₹89.5 lakh | ₹1.60 crore |
| ₹1 crore | ₹1.79 crore | ₹3.21 crore |
Use the annual inflation rate slider in the inflation adjusted SIP calculator above to model how different inflation scenarios affect your systematic investment plan's real purchasing power. The year-wise table shows the growing divergence between nominal and real values over time — the gap widens sharply in later years, which is when you need the corpus most.

Real Rate of Return on a Systematic Investment Plan
The real rate of return on a systematic investment plan is the return that exceeds inflation — the component of your return that genuinely builds purchasing power rather than just keeping pace with rising prices. It is calculated using the Fisher equation:
Real Return = [(1 + Nominal Return) / (1 + Inflation Rate)] − 1
At 12% nominal return and 6% inflation, the real rate of return is approximately 5.66% — not 12% − 6% = 6% as a simple subtraction would suggest. The Fisher equation is the mathematically correct approach, and it shows that even a 2% rise in inflation significantly reduces real returns. For a systematic investment plan to build real wealth, the nominal return must comfortably exceed the inflation rate — which is why equity funds, with their historically higher returns, are the primary vehicle for long-horizon SIPs aimed at maintaining purchasing power.
Frequently Asked Questions
Why should I use an inflation-adjusted SIP calculator instead of a regular SIP calculator?
A regular SIP calculator shows you nominal returns — the face-value rupee amount. But the purchasing power of money declines over time due to inflation. A target of ₹1 crore in 20 years sounds large, but at 6% annual inflation, it has the purchasing power of approximately ₹31 lakh in today's rupees. The inflation adjusted SIP returns calculator shows you both the nominal maturity value and the real value, so you can set your systematic investment plan targets in inflation-adjusted terms and avoid under-saving for goals that are decades away.
What inflation rate should I use for SIP planning in India?
India's CPI (Consumer Price Index) inflation has averaged approximately 5–6% over the past decade (2014–2024). The RBI's medium-term inflation target is 4%, with a tolerance band of 2–6%. For systematic investment plan planning, use 6% as a conservative estimate for most goals and 5% if you want a slightly optimistic scenario. For goals specifically related to education expenses, use a higher rate of 8–10%, as education inflation in India has consistently outpaced general CPI by 3–4 percentage points.
What is the real rate of return on an equity SIP?
For a systematic investment plan in equity mutual funds with a 12% nominal CAGR and 6% inflation, the real rate of return is approximately 5.66% per annum (using the Fisher equation). At 15% nominal return and 6% inflation, the real rate is approximately 8.49%. These real returns are still strong compared to FDs or bonds — but they highlight that a 12% nominal return does not mean 12% real wealth growth. The real SIP returns calculator above shows you the exact real rate for any combination of nominal return and inflation you enter.
Should I increase my SIP amount to account for inflation?
Yes. If your financial goal is defined in today's rupees (e.g., "I need ₹50 lakh for my child's education in today's prices"), you should inflate that target to its future value at your assumed inflation rate before entering it into the SIP goal calculator. Alternatively, a step-up SIP with an annual increment matching the inflation rate ensures your monthly contributions also grow in real terms over time — maintaining constant purchasing power of each instalment rather than letting inflation reduce the real value of a flat monthly contribution across your systematic investment plan tenure.
